There are massage devices for massaging parts of the body and in particular for massaging the feet. The devices consist of a ceramic cylindrical roller which is hollow and capable of holding hot liquid. The outside of the roller has a plurality of skull-cap shaped recesses which provide a suction type effect with the foot. This roller is designed to assist those who suffer from painful sore feet, muscular strains, varicose veins, backaches and knee and leg pain. Massaging the feet with this device helps to relieve tension and fatigue and can overcome circulatory problems caused by cold tired feet. The massage resulting in therapeutic action is accom plished by pressure of the foot on top of the roller which is moved in a recipricating rotary motion by the foot on a floor. The skullcap recesses provide additional massaging to the muscles in the foot. This type of cylindrical roller is shown in German Gebrauchsmusterschrift No. 1,692,898, issued Jan. 19, 1955.
One problem encountered with this device is that it moves too freely and has a tendency to get away from the foot as it is being rolled on the floor.
My present invention overcomes this problem and at the same time increases the massage capabilities and heat transfer capabilities of the heat from the liquid to the foot.
1 provide a hollow cylindrical massage device with skull-cap recesses, raised dimples, and raised ribs on the surface of the cylinder.
Other details, objects and advantages of this inven tion will become apparent as the following description of the present preferred embodiment proceeds. in the accompanying drawing 1 have shown a present preferred embodiment of the invention in which:
FIG. 1 is an isometric view of the hollow cylindrical shape massage device.
A hollow cylindrical massage device is generally shown as in FIG. 1. The surface of the cylindrical shape massage device 10 has a plurality of raised dimples 12, skull-cap recesses 14, and a plurality of ribs 16. The ribs 16 are shown extending longitudinally along the longitudinal axis of the hollow cylindrical shape 10. As shown in FIG. 1', the ribs 16 extend to one-half of the longitudinal axis. The other half of the longitudinal axis has a plurality of randomly placed raised dimples 12. The diameter of the cylinder becomes larger as the longitudinal axis approaches the center of the axis and the diameter of the cylinder becomes smaller near the ends and then increases to form a neck at each end of the cylinder. This gives the effect of a tapered convex shape on which the foot can rest. Flanges 18 and 20 adjacent to each neck form the ends of the cylinder. Each flange l8 and 20 has a plurality of ribs 22 and 24 extending radially about the longitudinal axis. The inside of the cylinder is glazed (not shown) to provide better heat conductivity to the outside surface of the cylinder which is preferably of ceramic material. One end of the cylindrical shape has a hole 26 to receive the liquid. To enhance the conductivity of the heat from the heated liquid to the foot, the raised dimples 12 are reinforced underneath with copper (not shown). The raised dimples 12 and the ribs 16 act as further resistance of the roller to the floor and at the same time enhance massaging surfaces on the foot.
1. A hollow cylindrical shaped massage device with skull-cap shaped recesses on the surface of the cylinder, the improvement comprising a plurality of raised dimples which are separated from the skull-cap recesses and are raised above the surface from which the skull-cap recesses are recessed.
2. The device as recited in claim 1 wherein the raised dimples are reinforced within by copper.
3. The device as recited in claim 1 wherein the cylinder has a flange adjacent to a neck at each end with each flange having a plurality of ribs and the cylinder diameter becomes larger as the longitudinal axis approaches from the neck to the center of the length of the cylinder.
4. The device as recited in claim 1 wherein the inside of the hollow cylinder is glazed.
5. The device as recited in claim 1 including a plurality of raised ribs along the longitudinal axis of the cylinder, the ribs are separated from the recesses and the dimples.
6. The device as recited in claim 5 wherein the raised ribs are reinforced within by copper.
